installation issue, help please

[David Peng]

Hi, all,

I am a newbie on ns3 and strictly follow the installation guide in tutorial:

./ns3 clean

./ns3 configure --enable-sudo --enable-examples --enable-tests

./ns3 build

Everything seems good. Then if I install with

./ns3 install

it reports error:

% ./ns3 install

Install the project...

-- Install configuration: "default"

CMake Error at cmake_install.cmake:41 (file):

  file cannot create directory: /usr/local/lib/pkgconfig.  Maybe need

  administrative privileges.

make: *** [install] Error 1

Finished executing the following commands:

cd cmake-cache; /opt/homebrew/bin/cmake --build . -j 7 --target install ; cd ..

If I run sudo:

% sudo ./ns3 install

Password:

Traceback (most recent call last):

  File "./ns3", line 1629, in <module>

    main()

  File "./ns3", line 1402, in main

    refuse_run_as_root()

  File "./ns3", line 1395, in refuse_run_as_root

    raise Exception("Refusing to run as root. --enable-sudo will request your password when needed")

Exception: Refusing to run as root. --enable-sudo will request your password when needed

Please help.

Thanks,

David

This is a surprising bug (surprising to me that we haven't noticed it
yet), but perhaps there are very few people who try to install to system
directories.

I opened a bug report to fix this:
https://gitlab.com/nsnam/ns-3-dev/-/issues/923

To work around this issue in the meantime, you can make a small change
to the 'ns3' script. Around line 1410, you will notice the following
command:

# Refuse to run with sudo
refuse_run_as_root()

If you comment out this statement, you should be able to run:

sudo ./ns3 install

and it will install to the configured location (which is /usr/local/ by
default, or can be changed at configure time with the --prefix option).

Yes, that works.
